Richter_Belmont Posted August 4, 2015 Share Posted August 4, 2015 Hello,i have a Gigabyte GA-H97-D3H mainboard with 16 GB DDR3 1600 RAM and a Xeon 1231v1 cpu. I checked the performance of the system with aida64 on a regular basis on Win 7 Pro. Memory clock and cpu clock in low power mode all were 800 Mhz, as it should be.Now, after an upgrade to Win 10 Pro (actually i did a clean install after the upgrade), aida64 only shows around 790 Mhz in the sensor panel (for both, CPU Clock and Memory Clock) and only 779 in the tool itself.Does anyone have an idea what the heck is going on here? Is it related to new chipset drivers? I have changed nothing on the system since the upgrade. voltage, ram timings... all the same. And the clocks are correct in BIOS.This is bugging me since 3 days now. Help would be much appreciated. Thanks in advance!! Quote Link to comment Share on other sites More sharing options...
Fiery Posted August 4, 2015 Share Posted August 4, 2015 I suppose the issue is due to the differences between the Win7 and Win10 kernels. That may cause a slightly unstable BCLK clock. You can check the measured BCLK if you issue a CPUID & MSR Dump. Go to AIDA64 / main menu / View, enable the Status Bar, then right-click on the bottom status bar of AIDA64 main window --> CPU Debug --> CPUID & MSR Dump. Copy-paste the full results into this topic, so we can check the output of all registers about clock measurement. Also, have you checked the BCLK and CPU core clock with other tools like CPU-Z? If it shows the same clocks, then it's not really the fault of AIDA64 Quote Link to comment Share on other sites More sharing options...
